IMPROVEMENT IN LASTING BOOTS AND SHOES.

Specification forming part of Letters Patent No. 210,920, dated December17, 1878; application filed November 11, 1878.

To all whom it may concern:

Be it known that I, GEORGE W. COPELAND, of Malden, in the county ofMiddlesex, in the Commonwealth of Massachusetts, have invented anImprovement in Lasting Boots and Shoes, of which the following is aspecification:

This invention has for its object the withindcscribed improvement inlasting the uppers of boots and shoes; and it relates particularly tothat portion of the lasting process which consists in securing upon thelast the upper, or upper and lining, after it or they have been fittedto the surface of the last,'and the edges thereof folded upon the bottomof the last, or upon the insole, by cement, in connection withfastening-strips united to the edge of the upper, or upper and lining,before or during the lasting process, for the purpose of uniting saidedge or edges to the surface of the insole.

In the drawing, Plate 1, Figure 1 is a perspective of an. upper adjustedupon a last, showing the edge upon one side united to the surface of theinsole by projecting strips, and the other side unfolded, showing theposition of the strips in relation to the edge of the upper and to thelining before the folding. Fig. 2 is a crosssect-ion. Fig. 3 shows theapplication of strips in securing the edge of an upper to the last whenused after the edge has been folded upon the insole, or upon the bottomof the last. Fig. 4 is a cross-section thereof.

Plate 2, Fig. l is a perspective of a last with the upper adjustedthereon, with the edge thereof united to the insole along one side by acontinuous strip which has been previously united to the cc ge of theupper or upper and lining. Fig. 2 is a cross-section thereof. Fig. 3 isa cross-section illustrating the modification.

Plate 3, Fig. 1 shows a fastening-strip when united to the insoleinstead of being united to the edge of the upper. Fig. 2 is anillustration of a strip applied to the surface of the insole in securingthe edges of the upper thereon in the lasting process. Fig. 3illustrates a detail in construction. Figs. 4. and 5 are crossscctionsfurther illustrating the invention.

Prior to the date of this invention the edge of the upper was secured tothe insole by pegs and tacks. Stitches have also been used for fasteningthe edge of an upper thereon by being taken from one side .to the otheracross the bottom of the last. These methods of fastening areobjectionable on account of the time it takes to use them.

It is very important, in view of the improvements that have lately beenm ado in machinery for lasting the uppers of boots and shoes whichautomatically adjust and clamp the upper to the surface of the last andfold the edge upon the surface of the insole, to employ a method forquickly uniting the edge thus folded to the surface of the insole orupon the bottom of the last in the lasting process. Tacks, pegs, andstitches will not answer this requirement, because they have to beplaced or taken one by one along the edge of the upper. Cement, ifproperly employed, can best be used for sccurin g a quick fastening ofthe edge of the upper to the insole.

In an application of even date herewith I have described a process forlasting the uppers of boots and shoes in which the cement is applieddirectly to the surface of the insole or to the inner surface of theupper, or upper and lining. In this improvement, instead of applying thecement directly to the surface of the insole or to the surface of theupper, I employ an independent fastei'iing-strip, which, preferably, iscoated with cement before the lasting process, although I do not confinemyself to this use of the strip, as the cement may be applied during theprocess. The fasteningstripshould be of thin flexible material. Paper,cloth, or leather will answer the purpose very well. It may be cut intonarrow strips and used along the edge of the upper, as illustrated inFigs. 1 and 3 of Plate 1, or it may be cut to a shape approaching thatof the insolo.

The fastening-strip, having been coated with a suitable cement or not,as may be desired, may be fastened to the edge of the upper, or to theedges of the upper and lining, or to the edge of the lining alone, inwhich case it would generally be necessary to fasten the edge of theupper to the lining to project there- 1 from, substantially as shown at0, Figs. 1 and ner they are united to the edge of the upper,

preferably before the commencement of the lasting process.

In Fig. 3, Plate 1, I show the fastening-strip c employed in uniting theedges of the upper by being cemented to the outer surface thereof acrossthe bottom of the last after they have been folded, and in this case thestrip may be fastened to the outer edges of the upper during the lastingprocess.

The fastening'strip maybe sewed to the edge of the upper before thelasting process, making the continuous edge A, as shown in Fig. 1, orthe continuous side, as shown at A, Fig. 3, Plate 3.

The strip, instead of being sewed to the edge -of the upper, or upperand lining, or instead of projecting therefrom at intervals, or insteadof extending across the bottom of the last from edge to edge, may besewed or otherwise united to the insole; and in Fig. 1, Plate 3, I showa strip united at the center of its width to the corresponding center ofthe insole. This strip 0, instead of being united to the insole, may bea leaf or lip skived from its edge inwardly thereon, as shown in Fig. 4,Plate 1.

Where an independent strip is used, it may be applied during the lastingprocess, and cemented to the insole, and to the entire edge of the upperfrom toe to heel. has been united to the insole before the lastingprocess, or has been secured upon the upper surface thereof, it may befolded upon itself, as shown in Fig. 5, Plate 3.

In employing this cemented strip as a unitin g medium, the strip isunited to the edge of the upper, or to the upper alone, or to thelining, in any of the ways herein mentioned; and it may be continuousalong the edge of the upper, it may be continuous along the sides only,it may be continuous at the toe and heel only, or it may be united tothe insole, or used in narrow strips extended across the insole fromedge to edge thereof, cemented to the outer edge of the upper, or it maybe a continuous piece, which shall unite the outer IV hen the stripedges of the upper by being cemented upon the same.

The cement, when used in any of these forms indicated, may be applied tothe strip before or during the lasting process. If it has been? applied,before the lasting process, it of course i will be necessary to moistenthe same at some} stage in the process.

The cement used may be of any suitable composition with sufficientcohesive property to properly unite the surfaces together.

A solution of caoutchoue and naphtha will answer moderately well. Fishsounds and glycerine properly prepared will do but I do not confinemyself to these compounds, as there are a great many that can besuccessfully employed for this purpose.

The advantages of this invention consist in the saving in timeobtainable in uniting the edge of the upper to the insole. Of course itwill be seen that by thus preparing the edge of the upper, or upper andlining, or the insole, with a means for fastening which can be employedin uniting the edge of the upper, or of the upper and lining, to theinsole in successive sections rapidly following each other, andpermitting both sides to be simultaneously fastened to the insole as oneof the sections, a very great economy in time is effected.

7 Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United State's- As a meansfor uniting the edgeof an up per or of a lining, or of both, to the surface of the insole inthe lasting process, a flexible strip or strips united to the edge ofsaid upper or of said lining, either before or during the lastingprocess, and cemented to the surface of the insole, or extended acrossthe same, and cemented to the edge of the upper or lining in uniting thesaid edge of the upper thereon in the lasting process, substantially asand for the purposedescribed.
